Be it known that I, CLAUDE Fox JAYNEs, a citizen of the United States, and aV resident of Seattle, -in the county of King and State of WVashington, have invented certain new and useful Improvements in Locking Devices for Turnbuckles, of which the following is a specification. L

My invention relates Ato `locking devices for turnbuckles, and therpurposeof myv invention is the provision of a loclringde-k vice of .extremely simple and inexpensive construction by means of which the turnbuckle is locked so as to prevent spreadbuckle. My

especially adapted, al-

locking device Iis though not necessarily, to that type of turnbuckle employed to adjustablyconnect the brake rodsv or other .parts of a lrailway car and .to` securely retain the turnbuckles against loosening .when subjected to the vif brationsof the car.

I will describe one form of turnbuckle and one' form of locking device, each em-y bodying my invention, and will then point out the novel features thereof vin claims.

In the accompanying drawings:-

Figure 1 is a view showing in side elevation a turnbuckle having applied thereto' one form of locking device embodying my invention.

Figure 2 is a transverse sectional view taken on the line 2 2 of Figure 1.

Figure 3 is a view similar to Figure 2 taken on the line 3-3 of Figure 1. Y

Figure 4 is an enlarged detail perspective view of the locking device with the locking dog omitted.

Similar reference characters refer to similar parts in each of the views. Y f

Referring specificallyto the drawing and particularly to Figure 1, I have here shown a conventional form of turnbuckle for connecting the brake rods or other parts of a railway car or similar vehicle, such/turnbuckle in the present instance comprising a rotatable connecting member K and two connected members D and D. The connecting member K includes an elongated body portion 15'of polygonal shape in cross the opposite ends thereof formed with reversely threaded extensions v16 and 17. The extensions 16 and 17 are adapted to threadedly engage the connected so that by rotating the condirection or the other membersD andD necting member in one Letters Patent.

a longitudinal adjustment Aof the connected members toward` or away from the connecting .member is effected. The connected members -are-off-like construction, and are rateatednpaa, 1922,@

provided with bifurcated extensions y18 ,andi

18 -forme d with openings at corresponding points to prov1deeyes for receiving connecting pms P. In the present instanceI have only shown one connecting pin locatedV in theconnectedmember D.

The locking device forming the subject matter of my. invention comprisesjin itsl present embodiment 'a bar B Vhaving alinear portion and a second'linearportion 20 formingin effect a continuation of :the p0rtion .119v but offset with'respectto the'la-tter by laterally bending the bar at the point indicated at 21. The portion 19 terminates in an eye 22,' while adjacent the bendl211a pairof arcuatelyl curved arms 23am-formed which coactto provide a guide bracket; The

free .end yof .the portion-20 terminates in a substantially U-shaped yoke 24, the parallel portions of which are formed with suitable openings to receive a pivot pin 25 (Figure 2).V Swingingly supported uponl thejpin 7 25 ata'point of the yoke 24 is a locking pawl L which as illust-rated to advantage in Figure 2 includes companion jaws 26 spaced `apart to accommodate the body portion 15 of the connecting member K.

In the applied position of the locking device to the turnbuckle as shown in Figure 1, the eye 22 receives the in 25 with the guide bracket 23 embracing t D. In this position of the bar the portion 19 lies contiguous to the member D` while the portion 2O is spaced from the connecting member K so that the locking pawl L can be swung to embrace the body portion 15 in the manner shown in Figure 2. With the locking device so applied' the bar B isfsecured to the connected member D and as the pawl L embraces the connecting member K, it will between the parallell portions ie connected member be clear that rotation of one member with respect to the other is prevented thus effecting a locking of the turnbuckle. The lockin Y device is preferably permanently attached to the turnbuckle by the pin P, and when it is desired to readjust the turnbuckle, the member K cany the pawl L to the dotted line position shown in Figure 1 and in which position thev body portion 15 is disengaged so as toV permit rotation of the connecting member.

vgVhat I claim is:` 1 1. In combination, a turnbuckle including a lconnectingmember and connected members, and a locking device comprising a. bar

secured to one ofthe connected members,

and a. paWl pivoted onthe bar to engage the.

connectingmember in a manner` to lock the latter against rotation with respect to the connectedmember upon Which the barv is supported. Y

2. In combination, a turnbuckleincluding a connecting member havinga polygonal shaped `body portion, and connected members, and alocking device comprising a bar supported "on one of the connected members,

a guide bracket formed on the bar and embracing one ofthe connectedl members, and a pawl pivoted on the bar to engage or disengage. saidbody portion for the purpose described.

3. Al locking/device fortiirnbiickles comprising a bar bent .to provide an offset portion, aneye formed on one end of the bar, a

be made` l e spirit of thefinventionf or the spirit and scope of the guide bracket formed on-'the bar intermediate its ends, and a pawl pivoted on the ofset portion of the bar and Y*including com panion Jaws.

4. A locking device for turnbuckles comprising a bar having Yan offset portion and provided with an eye at one end, a guide racket formed on the bar intermediate its ends, and a bifurcated the offset specified.

5. In combination, a turnbuckle including pawl projecting from portion as and for the` purposes a connecting member and connected meink bers, and a locking device comprising a bar secured to one of the connected.y members,`

and a pawl projecting from the bar to `engage tlie connecting member iii a manner to lock'tlie latter against rotation with is supported.

6. In combination,

one end on one oftlie connected members, a

guide bracket formed on the barand embrac-y ing one of the connected members, and a pawl projecting disengage 'the side faces of said polygonal body portion for the purpose described.
